Hans,
Sorry for the long delay in responding. Only just got around to testing
qv4l2.
All was well with qv4l2 on 4 camera's each capturing 25fps. Then when I
activated the 5th camera it all went pear shaped.
One camera dies, the image on its screen freezes on the last good frame.
All the other cameras get corrupt screens like line sync is missing.
Horizontal lines everywhere. See
http://www.doom.talktalk.net/2016-03-13-124047_1152x864_scrot.png.
I have seen this effect 4 years ago using zoneminder. I had two camera
working fine in zoneminder with motion detect recording. Adding two more
caused the effect in the screen capture. Eventually I put it down to
Zoneminder being very CPU hungry event at the lowest framerate. I
switched to motion and it would happily run motion detect on 6 cameras
using about 15% on one CPU (Dual core AMD Athlon(tm) II X2 270u
Processor 1600Mhz). Both zoneminder and motion were using the same old
tw68 module from github.
I have set up motion to capture at a relative low 2fps, it is all I
need. Can I set qv4l2 to capture at a lower rate to see if it resolves
the problem?
Thanks,
Tony.
